john has 12 pounds of dog food and is going to separate it into 3/4 pound portions how many portions will he get

John will get 16 3/4 pounds-units of dog food.

Step-by-step explanation:

The total amount of portions of dog food is obtained by dividing the total amount of dog food, measured in pounds, by the amount of dog food per portion, measured in pounds per unit:

John will get 16 3/4 pounds-units of dog food.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
